I am writing an AWS Lambda function in .NET Core 3.1. I am using Aspose.slides library in the AWS Lambda function. I am publishing the AWS lambda function as docker on AWS. Lambda function successfully gets published but when i test the Lambda it gives me the following error:
Aspose.Slides.PptxReadException: The type initializer for 'Gdip' threw an exception.
---> System.TypeInitializationException: The type initializer for 'Gdip' threw an exception.
---> System.DllNotFoundException: Unable to load shared library 'libgdiplus' or one of its dependencies. In order to help diagnose loading problems, consider setting the LD_DEBUG environment variable: liblibgdiplus: cannot open shared object file: No such file or directory
at System.Drawing.SafeNativeMethods.Gdip.GdiplusStartup(IntPtr& token, StartupInput& input, StartupOutput& output)
at System.Drawing.SafeNativeMethods.Gdip..cctor()
Even though, i am installing the libgdiplus package from the docker file but i am still getting the above error.
Docker file is:
FROM public.ecr.aws/lambda/dotnet:core3.1 AS base
FROM mcr.microsoft.com/dotnet/sdk:3.1 as build
WORKDIR /src
COPY ["Lambda.PowerPointProcessor.csproj", "base/"]
RUN dotnet restore "base/Lambda.PowerPointProcessor.csproj"
WORKDIR "/src"
COPY . .
RUN apt-get update && apt-get install -y libc6-dev
RUN apt-get update && apt-get install -y libgdiplus
RUN dotnet build "Lambda.PowerPointProcessor.csproj" --configuration Release --output /app/build
FROM build AS publish
RUN dotnet publish "Lambda.PowerPointProcessor.csproj" \
--configuration Release \
--runtime linux-x64 \
--self-contained false \
--output /app/publish \
-p:PublishReadyToRun=true
FROM base AS final
WORKDIR /var/task
COPY --from=publish /app/publish .
CMD ["Lambda.PowerPointProcessor::Lambda.PowerPointProcessor.Function::FunctionHandler"]
Any help would be much appreciated.
